Echo Echo Dot

We’ve all probably done it — gazed up at a passing jetliner and wondered where it was going and what adventures its passengers were embarked upon. While the latter is hard to answer, the former just got a bit easier: just ask Alexa what the plane is.

Granted, [Nick Sypteras]’s Echo Dot isn’t quite omniscient enough to know exactly what plane you’re looking at. His system benefits from the constraints offered by the window of his Boston apartment — from the video below, we’d guess somewhere in Beacon Hill or the West End — that offers a view of the approach to Logan Airport. An RTL-SDR dongle receives the ADS-B transmissions from all aircraft in the vicinity, and a Raspberry Pi does a lookup, picks the closest plane, and scrapes the departure and arrival airports from FlightRadar24. Alexa does the rest, but we have to confess that hearing “Boeing seven hundred eighty-seven” rather than “seven eighty-seven” would drive us nuts.

If you don’t have the limited view of an airport approach that makes [Nick]’s hack workable, maybe a plane-spotting robot camera would work better for you.
